Hi all
having an issue with an ARCH DC-DC converter I am using. it is an ST15-24F-15D model. ( 24v nominal in, +/-15V out, 15W ).
http://www.archcorp.com.tw/pdf/ST15.pdf
With the unit only drawing around 150mA on each line, we see excessive heat. 60 degrees C +.... This is intolerable in our design. Is it simply an issue with these type of converters and should we try a heat sink, or is something fundamentally wrong with what we are doing?
For the record we tried simply putting a high power 75 ohm resistor across each line, and 24V in, nothing else connected, and it still heated up... yet the manufacturers have informed us that it should not reach these sort of temperatures at this sort of load... ( It can supply +/- 500mA)
any ideas/wisdom?
